A.T. Robertson Commentary 1 Corinthians 16:10

"Now if Timothy come, see that he be with you without fear; for he worketh the work of the Lord, as I also do:" — 1 Corinthians 16:10 (ASV)

That he be without fear (ινα αφοβως γενητα). Evidently he had reason to fear the treatment that Timothy might receive in Corinth as shown in 4:17-21.
